Process Engineering

Steam plants

Most process engineering plants require steam for thermal processes or to supply their temperature control systems. The steam supply therefore meets an omnipresent requirement in the construction of process plants or when redesigning a factory. In the steam generator, water is heated to boiling point by the hot fire gases and evaporates. Saturated steam is produced, which collects in the steam chamber above the boiling water. Feed water and boiler water must meet certain requirements, in order to be able to operate steam generators safely and without damage.

These requirements are usually determined by the following influencing factors:

  • Design type
  • Operating overpressure
  • Operating conditions

Taking these functions into consideration, the requirements for the feed and boiler water are determined. Here, a distinction is made between the use of salt-free, low-salt and saline water for feeding the steam generator. In all cases, the feed water should be clear, colourless and free from suspended substances. To prevent corrosion, conditioning of the feed and boiler water is necessary.

Components of a steam generating plant

  • Steam generator
  • Feed water treatment (monitoring of feed water)
  • Start draining
  • Sludge removal (blowdown)
  • Mixing cooler (injection cooler))
  • Automatic conductivity measurement
  • Ph-value measurement
  • Supply unit
  • Exhaust gas heat exchanger
  • Chimney
  • Condensate regenerating unit
  • Steam pressure reducer
  • Condensate lifting device - recovery
